Hi! I'm planning on getting a TP Link Deco S4 mesh router. Right now, I just have an ISP modem plugged straight into my PC with no other gear in between. So here is my question: since the Deco S4 has two Ethernet ports and one goes to the internet (the input?), can I use the second port and connect it directly to my PC? Will that give me internet access, or do I still need a separate router or switch? I also plan to add more Deco nodes for wireless later. Honestly, I'm pretty bad at networking, so I tried watching YouTube tutorials but nothing really helped with this specific question. Sorry if my English is all wrong!

Hi! Thanks a lot! One more question: I am actually going to buy that mesh for my other vacation home (the setup we talked about before). If I set this up right now in my city house and then just move it later to the vacation place, will it work plug and play? Or do I need to reset or configure it again when I move it?
